Answer:
Once the fridge is moving you are still applying the same push force but now the opposing friction (now kinetic) force is less.
<h3>Hi!</h3>
The answer would be B. Lower.
Explanation:
This is because Force between two bodies is directly proportional to the mass of an object, but inversely proportional to the square of the distance between them.
So if the mass of the moon becomes twice, the force would also be twice as strong. (2 F ) , but if the distance is doubled, this force (2 F ) would be quartered ( 2F/4 = F/2 ) which would be half of the original force F.
Hence if the force is halved, the tides would be lower.

Answer:
the intensity of the light after passing through the two polarizing filters is 4.11 units
Explanation:
Given the data in the question;
the intensity of an unpolarized light; I₀ = 25.0 units
when the unpolarized light passes through the first polarizer, its intensity reduces to half of its initial value;
⇒ I₁ = I₀/2 = 25/2 = 12.5 units
the angle between the transmission axes of two polarizers is;
∅ = 55° - 0° = 55°
The intensity of the light after passing through two polarizing filters will be;
I₂ = I₁cos²∅
we substitute
I₂ = 12.5 × cos²(55)
I₂ = 12.5 × 0.3289899
I₂ = 4.11 units
Therefore, the intensity of the light after passing through the two polarizing filters is 4.11 units
Answer:
D. Photoelectric cell
Explanation:
Photoelectric cell converts light energy into electrical energy. They can do this because of something called the photovoltaic effect
